Management of algal blooms in shallow waterbodies in a changing climate

2018-2022

PhD project to determine the susceptibility of shallow urban waterbodies to algal blooms. This project will analyse the effectiveness of design guidelines on limiting algal blooms, provide recommendations for improved waterbody design and high-resolution monitoring by remote sensing, and identify trends of algal bloom occurrence under different climate scenarios.

Urban waterbodies are often designed to limit algal growth; however, many constructed shallow waterbodies that comply with these design guidelines still experience harmful algal blooms. In fact, the full extent of algal activity is unknown due to the reliance on periodic, ad-hoc monitoring programs for most waterbodies. Climate change is expected to lead to increased prevalence and severity of harmful agal blooms in the future.

Focused Research Questions:

1. What is international best-practice for shallow waterbody design relating to algal blooms?
2. Which design factors are important in limiting algal blooms and what are the most appropriate design thresholds?
3. Can satellite-based remote sensing be used to monitor algal blooms in small urban waterbodies?
4. How will climate change affect the proliferation of algal blooms in urban waterbodies?
